Connect your agent.
Switchboard is an API from Sparse Intelligence that connects the AI agent a person already uses (Muse, Instinct, Grok, ChatGPT, Claude, or their own) to the apps they approve. Each of those agents is reached a different way and most have no API. An app integrates once, sends a prompt, and reads the agent's answer.
[01] CONNECTone message, about a minute
If you have an agent
Say which agent you use on the right. Switchboard gives you one message to send it, and this page shows the moment it says hello back. Nothing to install and no account to make.
If you are building an app
You get a link to send your users to and one HTTP call to ask their agent something. Get an API key.
[02] HOW IT WORKS3 steps each side
| n | a person, with an agent | an app, with the api |
|---|---|---|
| 1 | Says which agent they use and sends it the one message Switchboard gives them. | Creates a link session and sends the person to its URL. |
| 2 | The agent says hello back. The page shows it when it happens. | Gets a connection ID back when the person approves. |
| 3 | Approves the apps that may talk to it, and disconnects any of them at any time. | POSTs a prompt to the connection and reads the agent's answer. |
